Yes. I committed the patch series together with modifications to wxt and qt so that both the current size and the current scale are always reported by "show terminal". Can you do the same for the windows terminal?

errors in script does not give error message with correct line number

Same as Bug 2238 https://sourceforge.net/p/gnuplot/bugs/2238/

Never mind. My fault. I managed to test with a mismatch between the gnuplot and gnuplot_qt versions. Usually that results in an obvious failure but in this case it was a silent error. I think I should add an explicit version check when the initial connection between the two processes is made.

I have played some, but only a little, with the qt and wxt plot + scale combination. I have not made up my mind what the ideal output of "show terminal" would be. But one thing is clear: it is pointless to report the scale value without also reporting the size in pixels. Since the purpose of "show terminal" is to allow reproducing what is currently on the screen, both the scale and size are necessary. As it stands now, a size is reported only if it was part of the original set terminal command. Furthermore,...

After thinking some more, I would prefer that both qt and wxt keep the current replot-on-resize tick-box (with your change to make qt work better) and add a new tic-box to control the scale option. I.e. just change the trigger for the new function from a separate button to a tick-box in the toolbox (wrench icon). I will go ahead and commit your earlier work and documentation for it.

That was surprisingly simple! Qt: The end result is great, but I find it confusing that it adds a separate button in the widget toolbar whereas the related setting "replot on resize" is a tic-box in the toolbox (wrench icon on the widget toolbar). As you note in the commit message, the old "replot on resize" tic-box did not seem to do anything. I think the new option should replace that tic-box rather than existing as a separate top level button. If nothing else, it is easier to see the current state...
